I am rdm lvl 20 and using enthunder can kill even matches with about 100-200 hp left and no magic.Killed about 6 or so today but no worm drop.try again tmoz.
You kill these things in a party while EXPing. A full party (6 people) around level 14+ can kill these things easily.
Also, note that the Fly TP move Cursed Sphere is water based, the proof of which is that BLU can learn it and it's a water elemental attack that bursts off Distortion and Reverberation.
I was pting in dunes when this thing poped up.I had a party of 13MNK/6WAR<-me 13DRK/6WAR 13BLM/6WHM 14WHM/7RDM 14PLD/7WAR 14DRG/7WAR. Our puller (The Drk) pulled it and it killed 3 of our party members.. Now it was only me the Drk and the Blm... So i used 100 Fists The drk used Blood weapon and the Blm used Manafont. We tried and tried but it didnt die! Then a stupid WHM come and healed me cuz i had 30 hp left and the damselfly attacked him and he died then a lvl 75 BLM/37WHM come and casted cure III on me :) So i was fully healed but not the DRK so i voked and had like 70hp left then the drk used Slice and it died ;D It was really close! (It was only 188 exp)
I remember one day...I was in a party of newbies (not noobs, there's a difference) when we're at the right level to fight damselflies...I had no idea that they linked, and I pulled one. There was one nearby. it linked.
WHM: zone to selbina! someone: Everyone, get your @$$3$ into selbina! Me: I'm goin, I'm goin!
so I begin running my little WAR **** to selbina and we pass up some more flies on the way. They linked. I couldn't count how many there were, but there were at least 10 of them....
WHM: OMG I guess the hell they DO link! WAR: Thanks alot, Eiyoko Me: I'm going to die~
Well, after that I was alot more careful about pulling these things.
